(STATEHOUSE) - The Senate has approved a bill setting boundaries on high-tech surveillance by police.

Legislators are also considering a bill to block police from using scanners to download information from your cell phone. But a second bill goes further, requiring police to get a warrant to use tracking devices, plant hidden cameras on private property, or use surveillance drones.

Bedford Senator Brent Steele says state police are already seeking warrants, but future departments might not. And Steele says as those technologies become more affordable for local police departments, it increases the possibility that some agency might try to cut corners.

The House will have to re-approve the bill because of a change made in the Senate to make clear it doesn't apply to ankle bracelets worn by released inmates on probation.
